Hi any of you guys out there got a AC/PC Adaptor that is compatable with the garmin 152 or any cable that allows you to connect it to my pc so i can download waypoints direct from my digital charts Regards Gary

I'm not sure what you mean by an AC/PC adaptor. You can connect the NMEA input/output port on your 152 to a serial port on your computer. Here is how to do it.
You can power your 152 from a 12volt battery while you are transferring data; red wire to positive and black to negative. You will need to ensure your 152 is set up to send and receive NMEA data. The method for this is given in your manual. Pages 83 and 84 show what you need to know.
